Synopsis
========
Format string vulnerability in the curses_msg function in the Ncurses
interface (ec_curses.c) for Ettercap before 0.7.3 allows remote
attackers to execute arbitrary code. (CAN-2005-1796)

Background
==========
ettercap is a multipurpose sniffer for switched LANs.

Description
===========
>From FrSIRT/ADV-2005-0670:
A vulnerability was identified in Ettercap, which may be exploited by
remote attackers to execute arbitrary commands. This flaw is due to a
format string error in the "curses_msg()" function of the Ncurses
interface (ec_curses.c) when processing specially crafted passwords,
which may be exploited by remote attackers to execute arbitrary commands.

Impact
======
A remote attacker could craft a malicious network flow that would
result in executing arbitrary code with the rights of the user running
the Ettercap tool, which is often root.

Affected packages
=================
ettercap in stable-rc and stable is affected. ettercap is already
version NG-0.7.3 in devel and test.
This is now fixed in all grimoires (ettercap updated to NG-0.7.3).

Resolution
==========
All ettercap users should upgrade to the latest available version:
        #scribe update
        #cast -c ettercap
